Discover indicators
Let’s set our health atlas. For this example we will use the Chicago
Health Atlas. We can do so by calling ha_set() with the
Chicago Health Atlas URL.
ha_set("chicagohealthatlas.org")
If we need to check which health atlas we are using, we can use
ha_get().
ha_get()
#> [1] "https://chicagohealthatlas.org/api/v1/"
We can list all the topics (aka indicators) present within Chicago
Health Atlas by using ha_topics(). The most important
column here is the topic_key. An individual
topic_key can be used to identify a topic within subsequent
functions.
topics <- ha_topics(progress = FALSE)

Note: topics can be derived from multiple datasets
or belong to multiple subcategories or keywords. Therefore, these
columns may be composed of tibbles or vectors. Filtering
topics via these pieces of information is still quite easy using
purrr::map_lgl().

Once we have a topic or topics in mind, we can explore what
populations, time periods, and geographic scales that data is available
at by using ha_coverage(). Again, the most important

desired.

We can even specify multiple topics, populations, and periods to get
data for. ha_data() will return a combined table with data
for every combination of topic, population, and period requested. A
warning will be given for every invalid combindation of topic,
population, and period requested.

Let’s map our data!
library(ggplot2)
plot <- ggplot(ease_of_access) +
geom_sf(aes(fill = value), alpha = 0.7) +
scale_fill_distiller(palette = "GnBu", direction = 1) +
labs(
title = "Easy Access to Fruits and Vegetables within Chicago",
fill = "Percent of adults who reported\nthat it is very easy for them to\nget fresh fruits and vegetables."

Our map looks pretty good, but perhaps there is a point layer that
may provide more insight into the spatial variation of the ease of
access to fruits and vegetables. We can use
ha_point_layers() to list all the point layers available in
the Chicago Health Atlas.
point_layers <- ha_point_layers()

Grocery store locations may be an important aspect of the ease of
access to fruits and vegetables. We can import this layer by providing
the point_layer_uuid to ha_point_layer().
grocery_stores <- ha_point_layer("7d9caf3c-75e6-4382-8c97-069696a3efbf")
Now that we have imported our grocery stores, let’s layer them on top
of our map.
plot +
geom_sf(data = grocery_stores, size = 0.5)
As expected, it seems that the areas with more grocery stores tend to
have a higher percent of adults who report that it is very easy to get
fresh fruits and vegetables.
This is a typical use case for the healthatlas in which
we explored every function that healthatlas has to offer.
Now it’s time for you to explore!
